. common test result indicator and a common recording unit are provided.The invention is directed, to recording of the test result along withidentifying data including the station at which the test was made andthe sequence or serial number of the test for the station. The inventionresides further in recording of information automatically with respectto any selected one of a plurality of information sources. The inventionalso contemplates novel means to preselect certain data for recordingduring a recording cycle of the machine. The invention has for otherobjects, the provision of:

Electrical cyclically operating means for causing recording of data by atypewriter and operations auxiliary to recording; e. g. tabular spacingand .carriage return operations.

'Serial numbering control means providing for serial numbering of thetests recorded for each test station or of the information pertaining toeach infomation source.

Automatic starting and stopping means for the motor` of a motor driventypewriter unit used as the recording unit.

Automatic means for unlocking the typewriter keys when the typewritermotor is under automatic control.

Novel means to preselect serial number counters for resetting and foreffecting resetting.

Novel means to eliminate recording of zeros by the typewriter prior totyping of the first signifi-f cant digit.

Other objects of the invention will be pointed out in the followingdescription and claims and illustrated in the accompanying drawings.which disclose, by way of example, the principle of the invention andthe best mode, which has been contemplated, of applying that principle.

Briefly. the niachine comprises a typewriter and arobot forautomatically operating the typewriter. The robot control the.typewriter to record information pertaining to tests made at aplurality of test stations. The kind of test made and the calculation ofthe test result are not subjects of the present invention and will notyl5 be discussed. The computed result of a test at any of the stations isgiven by a common result indicator. A serial number counter is providedfor each test station. When infomation relating to a test 'at a stationis to be recorded, the desired station is selected by the operator andclutch driven means brought into operation for a recording cycle. Duringthe cycle, the identity of the station is recorded, unity is added totheserial number counter of the selected station, the new serial number isrecorded, and the test result given by the common indicator is recorded.

The typewriter (Figs. 8, 9, 10)

80 Any suitable well known typewriter may be Sedes the recording means,but it is preferred to use the typewriter known as the Electromatic andthe general principles of winch are disclosed in Patents Nos. 1,775,055and 1,873,512.

Fig. 9 shows the keyboard of which keys I0 are the charac-ter keys, CRthe carriage return key, Tab the tabular spacing key. and SP the spacebar.

Briefly, referring to Figs. 8 and 9. depression of a key I0 releaseslatch Il from a. cam I2, permitting a spring-pressed lever I3 to movethe cam against the periphery of a friction shaft Il driven continuously.by the regular typewriter motor TM `(shown only in the circuit diagramFig. 12a). The cam l2 is rotated by the shaft to cause the cam carrieri5 to rock in a direction for depressing a link I8. Through linkage Il,the link I6 impels the type bar Il towards the sheet on platen 20 totype the selected character. In the final increment of movement of thetype bar, it strikes a universal bar 22 to actuate escapement lever 23for releasing the escapement mechanism to effect a character spacingmovement of the platen-mounting carriage 24 after the char- 55 ecter hasbeen typed. Depression of space bar a linkage 25 for actuating theesoapement lever y 23 to cause character spacing.

The carriage return mechanism is of the kind i disclosed in Patent No.1,955,614 and is set in operation by depression o! carriage return keyCR. As usual, line spacing occurs as an incident to carriage returnoperation.

The tabulating mechanism is set in operation by depression of key Tab,and is of the kind disclosed in Patent No. 1,935,436. The usual settabletab stops 2l control the extent of tab spacing upon each tab spacingoperation.

Element 2l is the usual settable margin stop to stop the carriage returnmovement when the left margin position has been reached by the carriage.

For each digit key, for the period or decimal point key, and for thespace bar SP, carriage return`key CR, and tab spacing key Tab, asolenoid I is provided. Energization of a key solenoid results inautomatic depression of the associated key or space bar. The solenoidsmay be distinguished by appending the designation oi the function 'ofthe related key or bar to the common designation 30 of the solenoids; i.e., solenoid BP is the solenoid for operating the space'bar and solenoidlli-i is the solenoidv for operating the key which causes typing otdigit 1. The keys may be manaully operated or. alternatively. may beautomatically operated by the solenoids.

The typewriter has the usual bar 32 (Fig. 10)

which moves upwardly to position for locking the key levers againstoperation when the regular typewriter switch TS is set in ofl" position.When this switch is moved to on" position, it rocks bar 32 down torelease the key levers. In the present case the typewriter is not onlyoperable manually but also automatically during certain cyclic periodsof operation oi' the robot. To keep the typewriter motor running duringthese cyclic periods only. when control of the typewriter by the robotis desired, the regular typewriter switch ls rendered ineilective andcyclic means provided to switch the motor on and ofi' automatically. Asthe locking bar l2 may be initially in locking position, a key unlockingsolenoid Il is provided which, upon energization, moves bar 32 down tokey unlocking position. The energization of the solenoid Il is eiectedduring the cyclic periods when the typewriter motor is automatically setrunning. When it is dired to operate the typewriter manually, thesolenoid It is disconnected from circuit and the regular typewriterswitch TS is rendered effective.

The robot tooth of which is adapted to engage in the notch'` of clutchcollar Il. Normally, the clutch dog 4I is held in disengaged position bya latch lever l! and a rebound latch 4I carried thereby. Uponenergization oi a clutch magnet l5, the latch lever releases the clutchdog which is enabled thereby to clutch the gear Il to the gear-3l forcommon rotation.

Gear I8 is meshed with a gear 41 on a shaft 48. The gear ratio is suchthat shaft 48 makes two revolutions to one'revolution of the gear 3l.Shaft 48 carries the brushes of emitters A and B of common construction.Also carried by shalt 48 are various Contact closing cams 5l for closingcam contacts CI to 'l in circuits which will be traced later.

The robot includes sequence or serial number counters, one for each ofthe test stations to count the number of tests made and recorded at therelated station. Each sequence counter, in this instance, has threeorders; hundreds, tens, and umts orders. The construction of onesequence counter is shown in Figs. 4 to 7. Each counter wheel l! has twoduplicate sets oi' digit positions 0 to 9. Fixed to the side of eachcounter wheel is a twenty-toothed ratchet Il having one tooth for eachdigit position. Coacting with the ratchet teeth of each ratchet I8 is adetent I'I for preventing clockwise rotation oi the ratchet andindicator wheel (as viewed in Fig. 4). Also coasting with each ratchetis the tooth oi' an actuating pawl 58. The pawi is pivotally carried bythe free end oi' the horizontal arm 59a of a. bell crank lever 50. Thevertical arm Mb of the lever constitutes the armature of the countermagnet lll. A spring 82 between pawl II and the arm 58a urges the pawlclockwise to maintain its tooth engaged with the ratchet. The back ofthe upper portion of the pawl Il is inclined and engaged with a bar 83,such engagement holding the pawl in position to inhibit thecounterclockwise rotation oi the ratchet when the pawl is in normal,lower position. Upon energization of the magnet 80, the lever I8 rocksclockwise and liits the pawl until its tooth is above the tooth nexthigher to the one previously engaged thereby. Upon deenergization of themagnet.l a spring Il connected to the arm b of lever M restores thelever in a counterclockwise direction, causing the pawl to descend.During this action o! the pawl, it turns the ratchet through one toothdistance and thereby advances the indicating wheel one value step fromone digit position to the next.

Secured to each indicating wheel is a rotor 1l of insulating material.The rotor carries axially spaced, separate brush pairs to coact withcontact segments imbedded in a xed moulding ll of insulating material.One brush pair 1l coacts with digital value segments 14-0 to B and acommon segment 14C. During each half a revolution of the indicatorwheel, or while it is being moved through one set of digit positions,one of the brushes 'll successively engages with the ten value segmentswhile the opposite brush 'll engages the common segment 14C. Twodiametricaily opposite similar brush pairs 12 are provided (Fig. 6).When the'indicator wheel is in a 9 digit position, the brushes 12 of onepair bridge the segments 9T and IIT. As the wheel moves on to 0position, the diametrically opposite brush pair 12 bridges commutatorsegments 'il and 'l1 for a purpose explained later. It will be evidentthat the brush pairs 1I alternate in function during successive hallrevolutions of the counter wheel.

It is understood that the counter wheels may be left blank in case it isnot desired or necessary to visibly show the counter reading.

Other parts of the robot will be described subsequently in theexplanation of the circuits and of the operation oi' the machine inselecting, reading out and recording information.

Circuits and operation Before starting operations under control oiA therobot, the operator may manually operate the 1 typewriter to type on asheet (Fig. 11) the date, other classifying information, and headingssuch as shown in this iigure. Alternatively, such information andheadings may be preprinted on the sheets. To prepare the typewriter forcontrol by the robot, a switch 8U is placed in lower position as viewedin Fig. 12a, rendering the regular typewriter switch TS ineifective tocontrol operation of the typewriter motor TM. The operator closes lineswitch LS, connecting a relay coil GE to a suitable voltage supply,thereby energizing the coil to close switch GEI. The closure of lthisswitch initiates operation of a motor-generator unit M--G to supplydirect current to opposite circuit sides 8I and 82.0f the robot.

The present disclosure takes into consideration ten test stations`referred to as stations I to IU. There are ten station relay coils NI toNIU (Fig. 12a) and ten associated plug sockets 88--I to IU for the tencorrespondingly numbered sta-A tions. To select a station for which-arecord is to be made, the operator connects a plug Wire (not shown)between the common plug hub 88C and the plug socket numbered similarlyto the de'- sired station; e. g. to select station 6, the plug wire isconnected between socket 83C and the socket 83-8. A circuit is thereuponcompleted from line side 8I via the socket 83C and the connected socket88-8 through coil N8 to line side .82. A recording cycle is theninitiated by depressing the print key (Fig. 12a) to close its contactsPK. This completes a circuit from lineside 8| via the print key contactsPK and normally closed relay contacts 84a through clutch magnet 85 (alsosee Figs. A1 and 2). Concurrently, a branch circuit extends from theprint key contacts PK via a line 85 through a relay coil 88 toV 6 plyline via now closed relay contacts GEI and a wire 84 through typewritermotor 'I'M and cam contacts C8 and a wire 85 to the opposite side of themain supply line. A parallel circuit proceeds from wire 8l via switch 8Uin lower position, through key unlocking solenoid 33 (also see Fig. 1)and via contacts C8 to wire I85. Solenoid I3 now unlocks the typewriterkeys for operation while the typewriter motor rotates shaft I4 (ses Fig.8). During theopen intervals of cam conf tacts C8, the typewritermotorstops running, .but

line side 82.l Another branch circuit is completed from key contacts PKvia relay contacts 84a and a line 81 (continue with Fig. 12b) throughthe pickup coil P'of a duo wound relay magnet 88 this magnet vianormally closed relay contacts 88a.

Energizedv relay coil 86 (Fig. 12a) closes-contact; lla to completethecircuit of robot motor' CM (also see Fig. 1).

' At this time, motor CM is in'operation and clutch magnet 48 isenergized.. Hence, a clutch cycle is initiated duringwhich the cam andemitter shaft 48 (Figs. 1 and v2) makes two revolutions. To maintaincoil 88 energized and motor CM in operation after release koi.' theprint key, energized magnet 88 closes contacts 88o (Fig. 12a). shunting.the print key contacts. Another shunt circuit for motor relay coil 88extends from line side 8I (Fig. 12b) via cam contacts C'I and a line 8U(continue with Fig. 12a) through coil 88 to line side 82.

During each of the two revolutions of shaft 48 occurring during a clutchcycle, the brushes 82 an'd 88 of Vemitters A and B (Fig. 12b) wipe theemitter spots, but during the first revolution only emitter A isrendered eilectiveand emitter B does not become effective until emitterA has' completed its functions.

Shortly after the clutch cycle starts, cam contacts CI (Figs. 3 and 12a)close. A circuit is thereby completed from one side of the mainlupduring these periods recording is not to occur. By this means, thetypewriter motor is set in operation only during desired portions of thecycle of the robot, and with switch 88 in lower position, the regulartypewriter switch TS is prevented rom initiating operation of thetypewriter mo- During the nrst revolution of cam shaft 48, f

emitter A is eilective while emitter B is ineffective until the 13thmachine cycle point (see Fig. 3). The current feed to brush 82 ofemitter A (see Fig. 12b) is through relay contacts 88h and Contacts 88hare closed at this time as a result of energization of magnet. 88 whichoccurred when the print key was depressed, as explained before. Contacts88a are normally closed and do not open until the emitter A brush hasreached its last spot, i. e., spot I2, as will be described later.

The current feed to the brush 83 of emitter B is through relay contacts88h and 88h. Contacts 88h do not open until the brush 83 reaches the I2spot of emitter B. Contacts 9812 will be closed when magnet 8U isenergized upon engagement of emitter A brush 82 withspot I2. Thus,contacts '88h close and contacts 88a open at the samea time and emitterA is rendered ineifective while emitter B is made effective.

The operations controlled by emitter A will now be explained. The rstsuch operation is the ,addition ofunity to the sequence counter of the-ation of one of the coils NI to NIU (Fig. 12a).

The energized coil will close its contacts a (Fig. 12b, lower right) andthrough these contacts, an impulse willlbe routed to the counter magnetor magnets of the sequence counter for the selected station. The countimpulse circuit will be completed upon brush 82 of emitter A reachingemitter spot I. Assume, for example, that station 8 has been selected;hence, coil N6 is energized and contacts "a of this coil are closed.When brush 82 engages spot I of emitter A, the following circuit iscompleted (Fig. 12b):

Count impulse circuit- Line side 8|, make and break contacts C8, relaycontacts 88h and 88a, brush 82, emitter spot I, and wire 88 to thecommon side of all the a contacts of coils NI to NIU; thence via closedcontacts a of coil N8 and a wire 88 through the units order countermagnet 8U of counter 8, to line side 82.

Energization of units order magnet 8U (also see Fig. 4) of counter 8followed by its deenergization as brush 82 leaves spot I of emitter A,causes the units order of this counter to advance one step,

. adding unity to its previous reading. If the units order is at "9" atthe time the count impulse cirasoaooo cuit is completed, the tens ordermagnet also will be energized to advance the tens order of the selectedcounter 1 step, thereby taking care of carry from units order to tensorder. As previously described, when a counter order is in 9 position,brush pair 12 is bridging contacts 0T and |0T (Fig. 8). Therefore, withthe units order in this position. the circuit of tens order magnet willbranch off from wire 00 via contacts 0T and IOT of the units orderbridged by brush pair 12, thence via one of the normally closed group ofa contacts of a reset relay coil Rl and through the tens order magnet 00of counter 0. If the tens order also is at "9" at the time the countimpulse circuit is closed. a branch circuit extends from line 00 via thecarry contacts 0T, |0T and l2 of the units order and the contact Riapreviously referred to. thence via the carry contacts ci' the tens orderand another contact Rta through the hundreds order counter magnet B0.Through the circuit or circuits described above, unity `will be added tothe previous count reading of the sequence counter of the selected teststation.

After brush 02 of emitter A has engaged spot I to initiate addition ofunity to the selected counter, the emitter brush successively engagesspots 2 and 0 to initiate automatic recording of the identifying numberof the counter in a field of columns under heading "Station" on thesheet (Fig. 11). In the assumed example, counter 0 was selected and coilN0 energized. Coil N0 closed contacts N0b (Fig. 12b). All the Nlb to Nlbcontacts are between a common wire |00 and a common wire |02. Wire |02is connected to a 0" line |00 which leads to the normally closed side ofrelay contacts a yof a relay coil |04 from which the 0" wire |00 extendsto a 0" wire |01 (Fig. 12e). This wire |01 is connected to the commonblade of switching contacts ZEa. When contacts ZEa are in normalcondition, they lead to the space bar operating solenoid 00SP of thetypewriter. When contacts ZEa are in shifted condition, they lead to the0 key solenoid 30. Contacts ZEa will be shifted. in a manner subsequent-`1y described, as a result of the typing of the ilrst significant digitin a record neld under one of the headings on the sheet (Fig. 1l). Thus,contacts'ZEa and their operating coil ZE are elements of aeroeliminationmeans to prevent typing of a mero preceding the firstsignincant iigure. When any of the test stations l to 0 are selected,the ilrst column of the neld under heading Btation" on the sheet willnot contain a significant digit. Hence, upon the emitter A brush 02engaging spot 2, a circuit will be completed through space bar solenoid00B? as follows, (start with Fig. 12b): From line side 0|. via contactsC0, 00h, and 00a to brush 02; thence via emitter spot 2 to line |00 andthe closedone of the contacts Nlb to Nlb to line |02, "0" line III, thelower side of contacts l00a,` and to connected 0" wire |00. The circuitcontinues through 0" wire |01 and the left side of contacts ZEa throughspace bar solenoid 00B?, and via normally closed contacts |00a and makeand break contacts Ci and C2 to line side 02.

When counter Il is selected. related contacts Nilb (Pig. 12b) areclosed. These contacts connect wire |00 to a wire |I0 leading to the "1"line |00. Hence. when emitter brush 02 reaches spot 2, a circuitproceeds through contacts Nllb to 1" line Ill. which connects to thelower side 0l switching contacts lllb. Fro'lnthere, the circuitcontinues via l wire Il! and the "lf line |01 through the 1 digit keysoicnoid 00| to the 8 common line I |2 of the digit and period keysolenoids 00-I to 0 and 30PER. The circuit is completed by way ofnormally closed relay contacts |00b through a coil ||3 and contacts Cland C2 to line side B2.

Coil H3, which is energized when any of the significant digit keysolenoids ll-l to 00-0 or the period key solenoid ll-PER is energized,closes contacts Illa (Fig. 12b) to pick up zero elimination control coilZE. Coil ZE closes stick contacts ZEb to provide a holding circuitextending from the side 02 through the coil, its b contacts and a wire||0 (continue with Fig. 12a) through normally closed relay contacts iliato line side 0|. Coil ZE shifts contacts ZEa (Fig. 12o). Thereafter,until coil ZE `is deenergized by opening ci its stick circuit, a "0impulse will be routed through` solenoid 00--0 and cause a "0 to beprinted, whereas prior to the shifting ol.' these contacts, thc impulsewas directed to the space har solenoid 3053i?.V

The units, order digit of the identifying number of the selected counteris typed when emit. ter A brush 92 reaches spot 3.' Spot l is connectedto common wire ||6 (Fig. 12b) connected to one side o! each of contactsNic to Nilo. Contacts Nlic, if closed, connect wire ||0 to thepreviously mentioned wire |02 which leads to the "0 line |00. The typingof the tens order digit of counter number I0 has caused zero eliminationcontrol contacts ZEa to be shifted. as explained before. Hence, thecircuit routed through the c contacts of coil Nil will proceed to thekey solenoid 30-0, causing a 0" to be typed in the units column underheading Station" (Fig. 11).

The closure of the c contacts of any of the other coils N to N0 willroute a circuit to the correspondingly numbered digit key solenoid 20.For example, with contacts Nic closed, the circuit initiated byengagement of spot I of emitter A with emitter brush 02 will extend fromline ||0 through contacts Nic to the "6" line |00, thence through thenormally closed side of contacts ist |00g and the 6" line |00 to the "8"line |01 (Pig. 12e); thence through solenoid 00-0 and through thepreviously traced path to line side 02.

After the station identifying number has been printed on a line of therecord sheet, the sheet will be tabular spaced to the first column lmderthe heading Test No. The tabular spacing operationis effected undercontrol of emitter A as the brush 02 engages emitter spot 0. A circuitis established which begins as in the previous emitter circuits andcontinues from spot 0 via a wire ||0 (turn to Fis. 12e) through the tabkey solenoid "TAB and by way of contacts |004,

Ci, and C2 to line side 02. Energization of solenoid IITAB causestabular spacing movement of the carriage to the first column of the TestNo. field.

In order to provide for elimination of leros preceding the nrstsignificant digit in the Test No. field, the zero elimination means isrestored to initial condition before typing begins in this lleld. Forthis purpose, coil ZE which was energlsed andheldasaresultof thetypingoftheflrstlllniilcant digit in the Station held is deenergiled beforetyping begins in the Test No. field. This is done by opening relaycontacts Illa (Hg. 12d) in the stick circuit of coil ZE. To opencontacta ||la, coil ||l is energized by a circuit established whenemitter A brush 02 engages spot l. This circuit extends from emitter Aspot l through normallyclosedrelaycontacts |00e. thenvia l 9 a wire |22(continue with Fig. 12o) through coil I I to line side 82.

After the tabular spacing of the typewriter carriage to bring the firstcolumn of the Test No. eld to typing position is completed, the readoutof the test sequence number begins. In order to allow suflicient timefor the tabular spacing to be completed before this readout occurs, thereadout is not initiated until the emitter A brush 92 reaches spot 8.Meanwhile, the tabular spacing, begun as the spot 4 was engaged by theemitter brush, willbe completed.

The test sequence number is readout of the selected counter. This testsequence number is the number of times the results of tests made at theselected station have been listed. Each time a station is selected, thecorresponding counter is stepped ahead one unit, as previouslyexplained, so that the counter corresponding to each station registersthe count and sequence of the test records for the selected station.When a counter is selected, the corresponding N coil (Fig. 12a) isenergized, as described before. Besides the other contacts closed by theN coil, it closes a group of d contacts (Fig. 12b), each in series withone of the common segments 14C of the selected counter. For example, ifcoil N8 is energized, contacts N8d are closed and the hundreds, tens,and units orders of the selected counter 8 will be read out by circuitsrouted through the NSd contacts and completed as brush 92 successivelywipes spots 8, 9, and I0. Assume,

for instance, that counter 8 registers 010. The hundreds order readoutcircuit starts as the other emitter A circuits and proceeds from spot 8to a line |23, the Nid contacts of the hundreds order, the connectedcommon segment 14C., thel brush pair 1|, the 0 value segment, the "8line |25; thence through the normal side of contacts |84a and by apreviously traced path through the solenoid 30SP. Energization of thissolenoid causes character spacing of the typewriter carriage. The "0preceding the first signiilcant digit of the sequence count is notprinted.

The tens order counter readout circuit is formed upon engagement ofbrush 92 with'spot 9 and, with the tens order in position 1, the circuitis routed via the connected digit 1 lines to solenoid 8|||. The circuitalso energizes coil ||8 which causes energization of coil ZE andshifting ofcontacts ZEa (Fig. 12e). Thus, the "0 in the units order ofcounter 8 will be readout when brush 92 engages spot I0 by a circuitrouted through the shifted side of contacts ZEa to solenoid SCI- 0. Inthe above manner, serial lnumber 010 in selected counter 8 is typed as10 in the Test No. nem.

The test result in the common result indicator is tobe recorded next.There are four orders of the indicator designated in Fig. 12o by TR..Each order has ten contacts corresponding to digits 0 to 9, as indicatedfor the tens order only. One of these contacts in each order is closedto indicate the digit of the result in the order. The means by which thecontacts are selectively closed is not part of the present invention.They may be considered as key contacts or as contacts of a relayaccumulator.

Before the test result is recorded, the zero elimination relay ZE isdeenergized. Upon engagement of brush 92 with spot a circuit isycompleted via normally closed relay contacts |88d and wire |22 (turn toFig. 12c) through coil ||8. Coil ||8 opens contacts ||8a (Fig. 12a),breaking the stick circuit of coil ZE (Fig. 12b).

, and b close.

^ Brush 82 moves on to emitter spot l2 and completes a circuit via awire |21 through the pickup coil P of a magnety |80. Contacts |3|IaContacts I38a complete a circuit from line 8| via make and breakcontacts C8 through holding coil H of magnet |38. Contacts |3817complete a circuit from line 8| via contacts C3 and in parallel throughthe pickup coils P of magnets 84 and 98. Contacts 88e close andestablish a circuit from line 8| via normally closed 89a relay contactsthrough the holding coil H of magnet 96. When cam contacts C3 opentdwardis the l'end of the 12th cycle point (Fig. 3), the holding coil ofmagnet |38 and the pickup coils of magnets 84 and 98 are deenergized.The holding coil of magnet 86 remains energized until contacts 89a. opensubsequently. Coil H (98) maintains contacts 96a open and contacts 96eclosed, respectively disconnecting the emitter A brush from circuit andconnecting the emitter B brush 98 into circuit.

The pickup coil of magnet 84 has been energized, as explained above, andcontacts b and c of the magnet closed. Through contacts b and camcontacts C1, a circuit is completed through holding coil H of magnet 84.This circuit is broken when contacts C'I open near the end of the 14thcycle point (Fig. 3). Coil H (84) opens contacts 84a (Fig. 12a) in thecircuit of clutch magnet 45. As a result, if the operator has beenunnecessarily holding the print key down, the clutch magnet will bedeenergized nevertheless. As long as the operator continues to hold theprint key down, another circuit for. coil H (84) is completed from line8| via the printdrey by contacts PK, wire 98 (turn to Fig. 12b), the bcontacts of magnet 84, and through coil H (84) to line 82. In thismanner, coil H is energized at about the midpoint of the clutch cycle toopen contacts 84a in the clutch magnet circuit and will remain energizedif the print key is held down. If the key is held down until camcontacts C1 reclose during the second half'of the cycle, the circuit ofcoil H (84) through these cam contacts will be re-established. The printkey must be released and then depressed again afterv cam contacts C1reopen near the end of the cycle before the clutch magnet 48 can beenergized again to initiate a new cycle.

Emitter B has been rendered effective nowby closure of contacts 98h.Engagement of brush 98 with spot completes a circuit from line 8| viacontacts C8, still-closed contacts 88D, and

now-closed contacts 98h to brush 88 and spot' which is connected to line||8 leading to the tab solenoid 8||TAB (Fig. 12c). Energization of thissolenoid causes tabular spacing of the sheet to bring the Result field(Fig. 11) to typing position. Spots 2 and 3 of emitter B are inactive toprovide time for tab spacing to be completed before recording of theresult begins. When brush 98 engages spot 4, a circuit is completed viaa wire |32 (Figs. 12b and 12e) through a magnet |88. Magnet |88 closesthe column of contacts 8 to 9 and c' (Fig. 12c) It will be noted thateach of the contacts 8 to 8 is connected at one side of thecorresponding 0 to 9 lines |81 and at the opposite side to acorresponding 8 f Ind .lb

ll II. For instance. with the I'contacts oi TR tens order closed, thecircuit is completed from line II via contacts .III-c, wire III, the Icontacts, wire III, contacts III-I and wire III-I through solenoid Il-I.

As soon as brush II o! emitter B leaves spot Ircoil III is -deenergizedand the readout circuit-for the tens order of TR is broken.' Engagementof brush II with spot l energizes a coil III (Fig. 12o). Coil III closesa column of contacts to read out the digit in the units time during areset cycle.

order of TR in the same manner as explained with respect to the relaycontacts oi' coil III and the tens order. After the units order digit istyped, a decimal point is to be typed. This is done as brush II engagesthe I spot, completing a circuit extending from this spot via a wire III(Figs. 12b and 12e) through the solenoid II-PER which operates theperiod key to print a decimal point. As this circuit includes coil III,zero elimination coil ZE will be energized and contacts ZEa shifted eveni! the tens and units orders of TR. both read zero. Thus, a zero in thetenths order or in both the tenths and hundredths orders will be typedas Os even if not preceded by a signincant digit.

Brush II after leaving spot I engages successively with spots 1 and I tocause successive energization ot coils III and III (Fig. 12e). Thesecoils close columns of contacts such as the III column to causesuccessive readout and typing of the values in the tenths and hundredthsorders of the indicator TR.

At certain times, it is desired to return the station counters to zero.Inorder to reduce the maximum current requirements oi the machine. onlytwo counters at a time may be reset. It is thus necessary for theoperator to make a selection ot the two counters to be reset at the sameFive reset cycles will be required to reset the ten counters. Theselection of the counters to be reset is made by manually setting aswitch arm I l0 (Fig. 12a) in engagement with one 0f the five terminalsdesignated I-2, 3 4, 8 8, l-I, and I-II. The two counters selected forreset are indicated by the designation of the terminal engaged by arm|50. For instance, if counters I and 2 are to be reset, arm III is setat terminal I-2. The operator then depresses the reset key (Fig. 12a),completing a circuit from line side Il via reset key contacts RK and thenormally closed d contacts of coil Il through relay coils III and III inparallel to line side 82.

Coil IUI closes its contacts e, f, g, h, and i (Fig. 12a) and opens itsa and b contacts (Fig. 12e, at bottom) and also its c and d contacts(Fig. 12b). The opening of contacts IIIIa and b prevents the making ofany key solenoid circuits. The open- Ernitter spot I of emitter B isconnected to a I line III which continues in Fig. 12e through thecarriage return solenoid IICR. Hence, after recording of the commonresult read out oi indicator TR, brush II engages spot I to energizesolenoid IICR. As a result, the record sheet (Fig. il) is line spacedand brought to position for receiving the next line of information. y

Emitter B spot II is connected to wire |22 which leads to coil I Il(Fig, 12c) Energization oi' this coil opens contacts Illa (Fig. 12a) tobreak the stick circuit oi' zero elimination coil ZE.

When brush II reaches spot I2, a circuit is completed from this spot viaa wire III to the pickup coil P of duo wound magnet II. Contacts IIbclose and establish a circuit from line side II through cam contacts CI,contacts IIb. holding coil H (II), to line side II. Magnet II openscontacts IIa to break the main circuits o! the holding coils of magnetsII and II.. The exact timing of the deenergization of these holdingcoils is controlled by cam contacts CI which are in shunt with relaycontacts IIa. Upon deenergisation oi' coils H (II) and H (II). contactsIIb open to disconnect the emitter B brush II from line side II. Bothemitters are now ineffective until a new cycle o! printing operations isinitiated.

As magnet II is deenergixed, relay contacts IIc (Fig. 12a) open,breaking the circuit oi coil II .through these relay contacts When camcon tacts C1 open, coil II is deenergized, and the circuit of motor CMthe motor.

Ii' the operator desires to operate the typewriter manually, switch II(Fig. 12a) is shifted to upper position. Closure o! typewriter switch Ththen establishes the circuit of typewriter motor TM as follows: Prom oneside of the supply line to wire Il. and via the upper blade of switch IIand switch TS through the motor TM and via con tacts GII to the oppositeline side.

opensto interrupt operationot ing of contacts IIIIc and d preventsmaking of the circuit of coil III (Fig. 12e) under control of emitter A.

Closure o! the e and l contacts of coil III establishes a stick circuiti'or coils III and III from line side Il via normally closed relaycontacts IIIb and contacts e and l o! coil III through coils IIII andIIII to line side I2.

With contacts e, f, and h of coil III closed and the switch arm |50 atterminal |-2, for instance, a circuit is completed from line side II viacontacts IIIb, in parallel through contacts IIIe and IIIIf, thence viacontacts IIIIh to switch arm III, thence via terminal I-I through areset relay `coil RI to line side I2. Similarly, if switch arm III wereat terminal I-4, reset coil RI would be energized; it at terminal l-I,coil Rl would be energized; if at terminal '1 -I, coil R'I would beenergized; and ii' at terminal I--II, coil R-I would be energized.

Closure of contacts f, e, and i oi' coil III completes a circuit fromline side II via contacts I IIb, parallel contacts IIIe and f, thencevia contacts Iilli to line Il, thence through clutch magnet Il to lineside 82. concurrently, a circuit branches Ofi' from the connection ofcontacts IIIi and line I1 through the pickup coil P of magnet II (Fig.I2b). vContacts' IIa close to establish the circuit of the holding coilH of magnet II extending also through normally closed relay contactsIIa.

.Coil H (II) maintains contacts IIb (Fig. 12b) closed to connect emitterA brush Il to line side Contacts IIc are held closed by coil H (Il) toestablish a circuit through motor relay coil II (Fig. 12a). Coil IIcloses switch IIa (Fis. 12u) to cause motor CM to be set in operation.

With the clutch magnet Il and motor CM now energized, a clutch cycle(Fig. 3) takes place. Within the 2nd cycle point, brush I! oi' emitter Ais engaged with emitter spot Lestabllshing a cire cuit from line side Ilvia contacts Cl, Ninna, brush I2, spot I, a line III (turn to Fig',12s), contacts q oi energized coil III, and through the pickup coil P ofa duo wound magnet III to line side I2. Coil P (IBI) closes relatedcontacts u, completing a circuit from line side II via a wire III nandnormally closed relay contacts Illia and now-closed contacts a (III)through holding coil 1H ot magnet III to line side Il. The holding coilmaintains the b contacts oi' magnet |53 closed to maintain a circuitthrough a reset signal lamp L. The signal lamp L will remain lit untilthe selected two counters are correctly reset to zero positions, in amanner explained later.

In accordance with the setting of switch arm |50 (Fig. 12a) one of thereset relay coils RI, R3', R5, R1, or R9 is energized, as previouslyexplained. Each of these coils controls resetting of the pair ofcounters designated by the terminals (Fig. 12a) to which they areconnected. Assuming, for instance, that switch arm |50 was set aty theterminal -5, coil R5 is energized and controls resetting oi' counters 5and 6. Referring to Fig. 12b,

coil R5 opens its ka group of contacts and closes its b group. WhileFig. 12b shows diagrammatically only counter 5 of the pair of counters 5and 5, it is understood thaty two more contacts a of lcoil R5 and threemore contacts b of this coil are associated with the circuits of counter5. Likewise, each oi' the other reset relay coils controls .a and bcontacts' of the related pair of counters.

Opening oi' the-a group of contacts of the reset relay coil breaks thecarry circuit paths between lower and higher orders of the selectedcounters, since carry is not desired during resetting operation. Closingof the b group of contacts of the reset relay coil for the selectedcounters prepares counter magnet impulsing circuits for completion undercontrol of the readout commutators oi the selected counters. The countermagnet oi an order will be energized and deenergized as many times asthe number of unit steps the counter order must advance to'reach zeroDosition. Thus, a counter magnet will be impulsed nine times if itscounter order is at "1.

The reset counter impulse circuits include make and break contacts C5(Fig. 12b). These contacts are connected between line side 5| and a line|50 common to the upper sides of contacts b to 1 of relay magnet |04.I'he upper sides of contacts |04b to j, when closed, connect line |50 tothe 1 to 9 lines |25 of the readout commutators.` At this time, magnet|04 (Fig. 12a) is energized by the stick circuit previously traced;hence, the upper sides of contacts |04b to j are closed. The upper sideof contacts |04a are not in circuit so that the "0" line |25 is notconnected to line |50.

Reset impulses will be fed to the counter magnets of both selectedcounters through the C5 contacts, the upper sides of contacts |04b toand the readout commutators of the selected counters and both counterswill be similarly reset. Resetting of only one selected counter will beexplained.

in detail. Assume, for example, that counter 5 is registering number098. Since no reset impulse canbe fed through the "0 line |25, thehundreds order of counter 5 will remain in 0 position. With the tensorder in "9 position, upon closure of cam contacts C5, a circuit iscompleted from line side 5I via contacts C5, line |50, the upper side ofcontacts |047', and the connected 9" line |25 to the 9 value segment ofthe readout commutator o! the tens order. T he circuit continues throughbrush pair 1| tocommon segment 14C, thence via a wire |5| and theconnected b contacts of reset relay coil R5 through the tens ordermagnet o! counter 5 and to line side 52. Contacts C5'break shortly afterand the magnet 55 is deenergized. 'Ihe energization and deenergizationof magnet 50 of the tens order of counter 5 advances this order to zeroposition where it stays. At the same time as the impulse was fed tocounter magnet of the tens order, an impulse is i 14 fed to thel magnet50 oi the units order. The latter impulse is routed through contacts|04i, "8

line |25, the "8 value segment of the units order of counter 5, thebrush pair 1|, segment 14C, and

It isvclear that nine reset impulses are the maximum required to resetany counter order, and resetting will be completed by the time onehalfthe clutch cycle has elapsed. After resetting has been eected, brush 92of emitter A engages emitter spot i2 and completes the circuit of coil P(|30). Contacts |30a close and establish the circuit of coil H (|30).Contacts |3011 also closevand pick up coils P of magnets 55 and 54.Contacts 95c close and establish the circuit of coil H (95). This coilwill now maintain contacts 95a open and 96D closed, therebydisconnecting vemitter A from circuit and connecting emitter B intocircuit.

Energlzed coil P (54) closes related b and c contacts. As before,closure of contacts b forms a circuit via cam contacts C1 for coil H(54). This circuit will open when cam contacts C1 break near the end ofthe ilrst revolution of cam shaft 45 (Fig. l) but will be re-establishedif the operator continues to hold the reset key down until the contacts`C1 reclose. Should the reset key be held down, a circuit for coil H(54) is established from line side 5| via the reset key contacts RK(Fig. 12a), a line |53 (turn to Fig. 12b), the c contacts of magnet 54and through coil H (54) to line side 82. This circuit will stay closed`until the reset key is released. Thus, coil H (04) will remain closeduntil the reset ke'y is released and cam contacts C1 open. lWhile coil H(54) is energized, it holds contacts 54d (Fig. 12a) open.

breaking the reset key circuit of coils |04 and*` Ymaintaining coil |05energized, and a new reset cycle can be initiated only'by releasing thereset key and depressing it again after contacts C1 open near the end ofthe clutch cycle.

Ernitter B has been rendered eil'ective, as previously explained, sincecontacts 95h have been closed. Engagement of brush 93 of emitter B withspot |0 closes the circuit of coil ||5 (Fig. 12C). Contacts ||5b open.,breaking the stick circuits of coils |04 and |05 (Fig. 12a). 'I'hc partscontrolled by these coils are now restored to normal condition.

Engagement of emitter B brush 55 with the |2 spot completes the' circuitof coil P (59). Coil H (59) thereupon is energized by a circuit and 11'when the counter order is in zero position (see Fig. 6). Referring toFig. 12a, the segment 11 of the units order of the lower number counterof each pair of counters to be concurrently reset is connected to thesegment 16 of the tens order, the segment 11 of the tens order isconnected to segment 16 of the hundreds order, the segment 11 of thehundreds order is connected to segment 18 of the units order of thesecond of the pair of concurrently reset counters, and so on 'to segment11 of the hundreds order of the second ofthe pair of counters which isconnected through aline IBB to line side 82. When all the orders of thepair o! counters are properly reset to zero positions, their brush pairs12 will connect the segments and 'I1 in series to line I". The unitsorder segment 1I of the lower numbered counter of the pair of countersto be concurrently reset is wired to one side of the c relay contacts ofthe related reset relay coil. Thus, if relay coil Rl is energized toselect counters I and 2 for resetting, contacts Ric are closed and ifthe counters have been properly reset to zero, a circuit will becompleted from line side Il via wire I through a magnet I, thence viacontacts RIc and the zero commutator elements 1l, 1l, and 'I1 ofcounters -I and 2, to line I and line side l2. Magnet Ill opens contactsIlia breaking thestick circuit of coil H (Ill). Contacts Ib open,breaking the circuit of lamp L. It will be noted that in Figs. 12a and12b, the hundreds, tens, and units orders are diiierentiated,respectively, by letters H, T, and U. In Pig. 12a, the group of zerocommutator elements of counter I are designated by #1, the group of suchelements of counter l by "#2, and so on.
